We’ve been here various times of the year and it’s always a nice visit. We park near the shops/fountain and spend hours hanging out, walking, window shopping, etc. We also go behind the huge hotel near the river. Sometimes it’s packed with an event going on and live music, sometimes hardly anyone around. But every time it’s a nostalgia feel or like a peaceful, step back in time. It’s nice 😊 We’ve been here various times of the year and it’s always a nice visit.

I like sitting and watching the river. Sometimes I eat lunch there.

I spent my Birthday at the Willamette River collecting shells and small colorful pebbles (bright orange are my favorite) for my Xmas Masons Jar craft. Made myself a healthy lunch, listened to my favorite jams, and wrote in my journal to memorate my special day. The river is clean, great fun for dates, family time, or taking your watercraft out for a spin. No public bathrooms on the river available...

You can drive&park your vehicle on the bank of the river. The bank is pretty rocky, be sure to take chairs for comfort. Coolers with food and drinks(no glass) allowed. Free life jackets and air pump for bicycles are available. The best part is it's all FREE! 🤣

The view is amazing. Great trail to walk along the river. Beautiful park. Great venue for movies and concerts in the summer time.

Nice park with amphitheater, boat ramp and beach. It was very dry when we visited, but there was a good portion of green grass and shade. A pretty good trail system is connected to the park. Lots of beach access from the trail also.
